Love.com works like this: Users put up a profile with information such as their age, occupation and photo and choose a screen name that can be linked to any AOL Instant Messenger, or AIM, screen name they have. Those looking for mates can then search, see who's online and send instant messages to people they are interested in. (This is more than they can do with AIM's current "find a buddy" tools.) Such messages are automatically forwarded to a recipient's regular instant-messaging account, and recipients receive alerts on their screen saying someone wants to contact them. They can choose to accept the messages or not. When not in a mood to date, people can set their preferences only to receive messages from buddy lists or block out certain users. Love.com also has an e-mail service within it for those weary of instant messenger. AOL also hopes that its large network can help attract some of the 80% of online single adults who haven't yet tried online dating, according to Jupiter Research.
